Pipe Connection; Three-Pass Discharge Pipe Connection; Condensate Water Pipe Connection; Power Connection - A.O. Smith HPW-60AT User Manual

Caution: When install leakage protection power cord, please refer to Fig.6 to prevent water flow
along power cord to plug and socket.

Pipe Connection

Connect a safety valve to the inlet tube (i.e. blue cap side) of heater, keeping arrow accord with water
flow (i.e. toward the heater) (Refer to Fig.7 for more detail). Connect a discharge pipe with safety
valve. Connect the hot water pipe to the outlet tube (i.e. red cap side).
For safety valve installation, please refer to chapter of "Safety Feature". If water pressure of inlet
pipe approaches or even exceeds relief point (0.8MPa) of the safety valve, please install a decom-
pression valve on the water inlet pipe away from the heater.
Water pipe and heater are only permitted to be connected by PPR pipe.
